Specification forming part of Letters Patent No'. 44,692, dated October 11, 1864.

To'all 'whom it may concern:

Be it known that I, CHARLES EDWARD SNEIIDER, of the city and county of Baltimore, in the State of Maryland, have invented a newfand useful Improvement in Cartridges and-I do herebydeclare the following to be a full and exact description of the same, reference being had4 to the accompanying drawings, making part of this speciiication, in which- Figure lis a perspective view of a cartridge illustrating my invention. Fig. 2 is a longitudinal central section of the same.

Similar letters of reference indicate corresponding parts in the two views;

This invention is an improvement in' that class of cartridges in which the powder is ignited by fulminate located within the vcartridge by the aid of a pin or rod which is struck by the hammer.

.The cartridge ismore particularly applicable to cylinders having a solid back and loaded be composed4 of thin, flexible rnetal. Anelongated ball, B, fitted within one end of the cartridge, -is formed on its. periphery latitudinally with a groove op crease, b, in which a portion of the shell is crimped or compressed, as shown at bl, in order to retain the ball in an immovable position when the vlatter has transmitted to it the force of the hammer, the shell Arbeing'held in position by its front end resting against therear end of the barrel, for which Apurpose the` said shell projects beyondl the front of the ball, as clearly shown in Fig. 2. b2 -may represent a percussion primer of any suit- `acted upon, the ball is caused to remain in a suiciently firm or rigid statev to withstand the force of the hammer, and thus the vprimer will be unfailingly exploded vwhen acted upon by the pin C. The dotsin Fig. 2 indicate the powder.

The rear end of the shell is closed, with the exception of a small aperture to receive thev pin C, and in this end is formed a concavity or countersink, a, the. edge of which projects somewhat beyond the protruding end of the pin C. Now, if the cartridge were inadvertently permitted to fall, it is manifest that the extreme end4 of the cartridge, or rather the edge of the countersink, would be the only part that would strike, and hence the pin is not liable to bedrivenagainst or explode the primer by any other cause than the action of the hammer, which is to be so arranged that its nose will 4enter the cavity a.

As the ball is completely enveloped by the cartridge-ease, it will be seen that the cylinder chambers 'which receive l the cartridge must be of greater caliber than the barrel.

The front of the shell will thus rest against the rear end of thebarrel, and so prevent the point of the ball entering the barrel and impeding therevolution of the cylinder.

It will also appear that a perfectly rm bearing is affordedv to the primer by the crimp b? preventing endwilse movement of the ball B within the shell A, and the 4latter being in its .turn preserved from endwise movement by 'resting against lthe rear ofthe barrel.

At the instant of the explosion the concave rear end of the cartridge being flattened against the bottom of the chamber, is thereby compressed around the rod C so as to'form iugvthe fulminate or cap on the base of the pin, which form a gas-tight joint by the con ball, I claim making the cartridge-case extend traction of the. rear of the ease around the ont as far as .the point of tire ball, so as t3 pin under the force of the discharge. abut against the rear end o thel barrel, an prevent: the forward motion of the ball or CHARLES ED WARD SNEIDER its protrusion into the 'bore previous to firing.
